This invention relates to bed springs, and is illustrated as embodied in a box type of spring which is suitable for use with either Y iron beds or wooden beds.

One object of the invention is to provide a spring construction or especially a box spring frame construction which while simple in'construction and light in weight will fit both metal beds and wooden beds, lying l0 as low as possible 'in each, and which will furnish a suitable tacking surface for a complete fabric cover. In order for a spring to lit a metal bed it is necessary for it to have projections below the supporting surface,

these projections fitting between the side angles or side rails of the bed, to hold the spring in place. In order for the spring to t a wooden bed, it is merely necessary that it rest on the slats, but unless the downward projection spoken of above is minimized, the spring will extend undesirably high. In both kinds of bed, it is desirable, according to present fashions, to keep the upper surfaces of the springs and of the mattress as low as possible. It is believed that this desirable feature has been obtained in the present invention.

With these and various other objects in view, the invention may consist of certain novel features of construction and operation,

as will be more fully described and particularly pointed out in the specification, drawing and claims appended hereto.

In the drawing, which illustrates an embodiment of the device and wherein like reference characters are used to designate like parts,

, The presence of such space would of course mean that either the covering would lbe un- -with transverse members 12 and end transverse members 13 arranged at suitable intervals for supporting the springs. On each of the transverse members 12and 13 are preferably located a plurality ofcoil springs 14. These springs are tied together in any suitable manner, as by springs 15. According to my invention, the cross members 12 do not extend the full width of the frame, as was the former practice, but merely extend .to approximately the transverse middle of the longitudinal members, as shown best in Fg- Beyond the ends of the-transverse members 12 are secured tacking'strips 16 65 which run the full length of the longitudinal members exceptthat they end-abut the end transverse cross members 13 instead of extending alongside of them. These tacking strips 16 together with the end transverse?l members 13 present uniform surfaces both on the side andV on the bottom. This greatly facilitates covering the box spring, as the covering 18 may be folded around the tacking strips 16 and tacked thereto. As there is no projection below the transverse members 12 it is no lon er necessar to make s ecial 7 l l n u n provision for avoiding leaving space between the covering and the transverse members 12.

desirablyloose or that it would be torn when the spring was rested improperly on thecovering between the downward projectionsr When the box spring is used with a metal bed, it is set on the side angles, as shown in Figures 3 and 4, with the transverse members f12 and the tacking strips 16 extending down between the side angles 20. Thus it is seen that the majority of the springs have their supporting transverse `members extendingY TEE bottom ends substantially at the level of the side angles 20. l/Vhen the box spring is used in a wooden bedstead, the transverse members 12 and tacking strips 16 rest on bed slats 22. Here it is seen that the majority of the springs are separated from the bed slats by only one thickness of board instead of by the transverse members 12 plus a downward projection therebelow which was formerly considered necessary to hold the box spring in place in a metal bed frame.

This invention, therefore, accomplishes three new results at once. First, it puts the interchangeable bed springs one board thickness lower on the metal frames by indenting the ytransverse members so that they may iit between the side angles 2O and hold the spring in place. Second, in a wooden bed frame it lowers the springs by the thickness of the downward projection which was formerly considered necessary below the transsubstantially flush with the bottom surfaces of said transverse members, said transverse members and molding strip presenting a substantially straight longitudinal edge and leaving a suhcient outer margin portion of said longitudinal members exposed to rest on the side rails of the bed.
